Painting yog lub ntsiab lus dav dav rau txheej txheej txheej txheej ntawm cov khoom lag luam. Nws feem ntau yog siv rau cov roj pleev xim yas, silk screen printing thiab pad printing; Xim hloov thiab tshuaj ntsuam luam ntawv ntawm EVA, roj hmab thiab lwm yam ntaub ntawv khau. Yuav tsum muaj lub tshuab txhaj tshuaj kom tiav cov txheej txheem no. Koj tuaj yeem xaiv cov roj pleev matt, semi matt, siab gloss, thiab lwm yam raws li koj xav tau.
Vim li cas txau roj?
Kev txhaj tshuaj roj rau ntawm lub ntsej muag ntawm tes tuaj yeem ua rau nws zoo nkauj dua. Rau qee qhov, cov tshuaj tua hluav taws xob hnyav tuaj yeem ua rau cov neeg siv khoom muaj kev cuam tshuam zoo dua thiab txhawb kev noj. Ntxiv mus, cov roj txau muaj qee yam kev tiv thaiv ntawm tes board thiab cov khoom. Coj cov duab ntawm cov hlau nto ua piv txwv. Kev pleev xim ntawm hlau nto yog ib txoj hauv kev los tiv thaiv cov hlau los ntawm oxidation thiab corrosion. Cov xim zoo xim txheej tiv thaiv txheej yuav tsum ua kom tsis tu ncua, tsis tu ncua thiab ua ke zoo, thiab tuaj yeem dhau los ua qhov cuam tshuam rau inhibit qhov ntxeem tau ntawm corrosive media.
Muaj tsib kauj ruam ua rau kev txhaj tshuaj roj:
1. Annealing: Cov yas yog ib qho yooj yim los tsim cov kev ntxhov siab sab hauv thaum lub sij hawm molding, thiab qhov kev ntxhov siab yog yooj yim tawg tom qab txheej. Annealing kev kho mob los yog tag nrho lub ntsej muag kho yuav siv tau los tshem tawm kev ntxhov siab. Kev kho annealing yog kom sov ABS yas molding qhov chaw rau qhov kub thiab txias hauv qab lub thermal deformation kub, uas yog, 60 degree, thiab ua kom kub rau 2h. Txij li cov txheej txheem no yuav tsum muaj kev nqis peev ntau ntawm cov cuab yeej siv, tag nrho cov thev naus laus zis kho tshuab tuaj yeem siv tau, uas yog, kev daws teeb meem uas tuaj yeem tshem tawm cov kev ntxhov siab sab hauv ntawm cov yas tuaj yeem tsim kho los kho qhov chaw ntawm cov yas rau {{3 }} feeb ntawm chav tsev kub.
2. Degreasing: Qhov saum npoo ntawm cov khoom yas yog feem ntau stained nrog roj stain, tes hws thiab tso tawm tus neeg sawv cev, uas yuav ua rau cov adhesion ntawm cov xim tsis zoo, thiab cov txheej yuav tawg, npuas thiab poob tawm. Kev tshem tawm roj yuav tsum tau ua ua ntej pleev xim. Cov khoom yas feem ntau yog ntxuav nrog roj av lossis cawv. Tom qab cov tshuaj degreasing thiab tshuaj degreasing, cov seem lye nyob rau saum npoo ntawm lub workpiece yuav tsum tau muab ntxuav kom huv si, thiab thaum kawg ntxuav nrog dej ntshiab, qhuav los yog qhuav.
3. De electrification thiab dedusting: cov khoom yas yog cov insulators, thiab cov nplaim tsis kam yog feem ntau txog 1013 Ω, uas yog ib qho yooj yim los tsim hluav taws xob zoo li qub. Tom qab hluav taws xob, nws yog ib qho yooj yim kom nqus plua plav zoo hauv huab cua thiab txuas rau saum npoo. Vim tias nws yog qhov nyuaj heev los tshem tawm cov hmoov av electrostatic adsorbed nrog cov cua tshuab dav dav, nws yog qhov zoo dua los siv cov cua kub siab ionized rau ib txhij tshem tawm cov plua plav electrostatic.
4. Txau: lub thickness ntawm cov yas txheej yog 15-20 μ m. Feem ntau nws yuav siv 2 mus rau 3 lub tsho ntawm cov xim kom tiav. Qhov thib ob txau yuav tsum tau nqa tawm tom qab thawj zaug txau yog qhuav rau 15 feeb. Qhov saum npoo uas yuav tsum tau ci yuav tsum tau txau nrog cov xim pob tshab. Cov coated qhov chaw muaj me ntsis cuam tshuam rau cov nplaim retardancy.
5. Qhuav: feem ntau, xim yog ci ntawm 150-180 degree rau 20-30 feeb; Ci cov xim yas ntawm 60-80 degree rau 20-30 feeb; Qee cov xim tshwj xeeb tuaj yeem qhuav hauv qab lub tsev xog paj.
